COMPOUND OF ACTIVE MASS FOR MANUFACTURE OF NEGATIVE ELECTRODE OF METAL-HYDRIDE ACCUMULATOR, AND METHOD FOR OBTAINING ACTIVE MASS

摘要

FIELD: electricity. ^ SUBSTANCE: powder of intermetallic compound containing dopants, with carbonyl nickel powder at the following component ratio, wt %: intermetallic compound with dopants 85-94, carbonyl nickel 6-15. The obtained mixture is subject to chemical nickel plating in presence of sodium borane and 20% water solution of nickel sulphate at the following component ratio per 100 g of mixture: sodium borane 2-3 g, water solution of nickel sulphate 63-64 ml. After chemical nickel plating the obtained mixture is dried and organic binding agent is added in ratio of 1.5-2.5 g of binding agent per 100 g of dry mixture. ^ EFFECT: higher specific discharge characteristics of metal-hydride electrode and simpler technical manufacturing process of active mass with simultaneous reduction of its manufacturing cost. ^ 5 cl, 3 ex, 2 tbl
